The base of the stationary part is indicated at 7 and upon it are erected bearings 8 for a rock-shaft 9 to which the starting lever 10 is secured, said starting lever projecting up through a slot 11 in the top 5. The starting lever ismoved longitudinally of the machine to the end 12 to start the machine to perform the operation. of multiplication and to the end 13 to start the machine to perform the operation of division, the rock-shaft 9 slidslot, and it must be retained in such position 'ing as the lever is thus moved.

.Be it known that 1, WILLIAM F. Hans- STEIN, a citizen of the United States, re-

This invention relates to calculating ma chines such as that which forms the subject matter of U. S. patent to Alexander Rech nitzer, No. 809,075, granted Jan. 8, 1906.

In that machine the various operations of addition, subtraction, multiplication and division are performed and the machine comprises in its mechanism a starting lever which to start the machine to multiply must be moved to one end of a slot through which it projects, while to start the machine to divide, it must be moved to the opposite end of the which depresses and ops behind the tooth 19 to retain the lever inthis starting position. At 21 there is provided another pawl 22 which is in turn provided with .a tooth 23 which bears the same relation-toxthestarting moved to end 12 of the slot to start the dive sionoperation) as the pawl -17 and ltStOOtll startin positionbefore described. I

To the top 5 at 24 is pivoted a disk 25 which is connected by awrist pm 26 and a.

' said plate to the ri lever free to be moved as maybe desired to link 27 to the pawl 17 and bya wrist pin 28 and link 29 to the pawl 21 so that the tooth ends of both pawls are yieldingly and normally held in position to receive and enga e the starting lever when moved to either of the ends 12 or 13 of slot 11 to start the machine, and so that one releasing mechanism will simultaneously operate both awls to release .the' starting lever from eit er posi-- tion.

On the underside of the top 5 is a plate. 30 slidably secured by screws 31 passing.

throu h a slot 32 into top 5, said: slotted plate having a projection 33.0utside the edge of top 5 in the hue of travel of a pin 34 (which I denominate a terminal in) carried by the sliding carriage. When t e machine'is performing the operation of division, this terminal pin is inserted in a ole 35 and when multiplication is.being performed, in a hole 36, said holes being in the sliding-carria e.

The terminal pin being in, say ho e 35,'the handle is moved to when the machine will start to perform an o eration in division, t e right during such operation. terminal pin at the end of the operation strikes the projection-33 of plate 30, it moves ht against an arm 37 of awl 21 which tips t e'pawl, thus drawing on ink 29, turnin'g'di'sk 25,-drawing on link27 and withdrawing the' tooth of pawl 17 out of contact with the starting lever leaving said start another operation. In-theo eration of multiplication, theterminal pin in ole 36, at

, the end of theoperation, strikes projection 33 of plate 30, and causes it to actuate plate 30 against arm'37 of pawl 21, which tips the paw and removes-its tooth out of contact ,with the starting lever leaving the leverfree to befmoved to any desired position to start another operation.

What I claim as new 1s:-

1. In a calculating machine provided with a plate having a slot therein, aslidable shaft, a lever secured to the shaft, roje'cti'n through the slot and adapted to he move from anormal intermediate position to either end of said slot, and a pawl automaticallyoperated to secure the leveragainst accidental movement from either-end position,

2 In a calculating machine provided with a plate having a slot therein, the combination therewith of a lever adapted to be moved to either end of saidslot, a pawl automaticall operatedto'secure I the lever against accid ental movement fro'mieither of such positions, a sliding carriage, an adj thereon, and means actuated by said stop at end 12 of the slotll,

the carriage sliding to in either of such ustable stop.

the termination of the carriage movement to release the pawl.

3. In a calculating machine the combination with the stationary top provided with a slot having an end space, a starting lever adapted to be moved into said end space to start the machine, a pawl normally in positionto secure the starting lever in such position, a sliding carriage, a terminal pin thereon, a slidable plateon the stationary portion of the machine in the ath of the pin, and connections whereby the pawl, at the termination of the o eration of the carriage, is released by said slidable plate.

4. In a calculating machine the combination With thestationary top provided with a slot having two end spaces, asta'rting lever adapted to be moved into either of said end spaces to start the machine, two pawls normally in position to secure the starting lever in either of such positions, a sliding carriage, a.

terminal pin thereon, a slidable plate on the stationary portion of the machine in the path of the pin, and connections whereby the pawls, at the termination of the operation of the carriage, are released by said slidable plate.

In a calculating machine the combination with the stationary top provided with a slot having an end space, a starting lever adapted to be moved into said end space to start the machine, a pawl normally 1n positionto secure the stationary lever in such position, a disk pivoted to the stationa top of the machine, a link connecting it will -i the pawl, a sliding carriage a terminal pin thereon, a slidable plate on the stationary portion connections whereby t e pawl, at the termination of theeration of the carriage, is

released byisaid s idable plate.

6. In a calculating machine the combination with the stationary top provided with a slot having two end sp spaces to start the machine, two pawls nor mally in position to secure the starting lever positions, a disk pivoted to the stationary top of the machine, two links connecting itwith the pawls, a sliding'carrlage, a terminal pm thereon, a slidable plate on the stationary portion of the machine in the path of the pm, and connections whereby the pawls are released by said slidable plate.
